Application filed December 17.1 915. o Serial-No. 67,364.

To all whom it may concern:

Be it known that I, JAMES S. KENYON, a citizen of the United States, residing at Providence, in the county of Providence, Stateof Rhode Island, have invented certain 7 new and useful Improvements in Heel-Na ls,

of which the following is a specification.

p .vMy invention is an improved nail ror use in attaching heels to boots or shoes. The object of my improvement is to provide a nail having a relatively long shank or body portion with a point at one end and acollar at the opposite end, above which is. an extension, of substantiallythe same diameter as the body of the nail, formed with annular grooves or corrugations to adapt it to seiwe as a holding-means for the top lift of the heel.

In attaching heels to boots or shoes the main portions of the heels consisting of a certain number of lifts are first nailed onto the sole and then a top lift is applied to provide a finish for the heel. In some cases the top lift-is merely glued or cemented on to the other lifts to cover the heads of the nails with-which the main portion oft the heel is asten l;-;while insot ersin tano s it has; llma dieeninieonosechto neoe zeet l ez epih nmansmimstensims castle na sew iich 1 lfystnpatlseofimilteliifint ofi ihe nililki w lfidw fiastert has heretoiilere hee imep 'seihteemr galpyia had harmgmcelles mopesen te nd stsragmne l-itheizl thdthot t emamcl e itgen oisthgdiesk and In clnalsnthe mne tsneiee eboiie hllel tulltmvh ilp ifido habafl efitehs'mfi ahevtophdifin nh ndtpeed tte eesiii nen re Wfiehttne (torment-marinas heseto erenued roitrhis enpnsedroneie s:iuneemeene eend too e anainaiiu pseoztethgeasese tste mime nhe'no oreposarotm ee medalis -steam v nusiiimr eholdinea peansnrzerten nenlfgy seaznririgngl mlareithextcopil tt eiztrlimlme hoi ie annoy mended,

reas ess ent!amen Best AvAtLA complished by a simple rolling action in grooved dies by aprocess which does not add materially to the cost of manufacture of the nail. That is to say, it, costs practically no more to roll the extension E- with grooves than to form the collar C, and as a matter of fact both operations whether performed singly or together may be accomplished at very slight expense. It will therefore be seen that my improved nail may be manufactured in accordance with the usual them and clenchingits point P through the sole S and a part of the upper U. The collar C on the nail N will thus abut the face of the last lift 5/ of the heel, to serve as a holding-means therefor in the usual manner, and projecting outwardly beyond the main part of the heel is the extensionE of the nail arranged to' receive the top lift L. The top lift Lis applied by spanking it onto the heel in the well known manner as usually employed to cause the nail ends or extensions E to be driven into the leather. The rounded end of the extension E adapts it for easy penetration into the top lift L and the corrugations or annular grooves e allow the leather or other material to expand therearound to take a grip on the nail. That is to say, as

" the lift L is spanked into place the exten- 1 sions E will penetrate its material while the fibers thereof expand into the grooves or corrugations e to frictionally grip'the -lift.

' concealed from view so that a neat and thereto to effect a secure fastening. It will be seen that the extensionsE do not pro ect-- beyond the outer face of the liftLbu'tare finished appearance is given to the heel. In

this manner the top lift L can be united to the heel without any other fastening-means such as cement or glue and with the nails T entirely concealed from view. It has been demonstrated thatthe novel form of extension E on the nail N as'here shown provides for a most secure fasteningmeans for the top lift and is much superior in this respect to similarly formed nails heretofore employed for like purposes. As before stated I am aware that it is not new in the art to provide a nail with an end collar having an extension projecting upwardly therefrom for fastening the top lift to the heel. Heretofore however, such nails have BLE CGP been open to certain objections; first, that ii they were ineflicient for the purpose intended, and second, that they were too expensive to manufacture to adapt them for general use.

. In one form of such a nail as previously 7 used the extension above its collar is pro vided with concaved side faces which taper outwardly to a relatively broad driving end. This end being considerably larger than the body of the nail it has been found difficult to drive the top lift onto it without breaking the fibers of theleather and furthermore the lift is not securely fastened after it is once in place. That is to say, the leather does not grip the sides of the extension on the nail as in my improved construction and thenail is therefore not as efficient for holding the lift in place. Another objection to this form of nail as just described is that its extension cannot be formed by a rolling process but must be constructed by more complicated operations. This renders the nail more expensive to manufacture so that it is not adapted for general use.

Another form of nail previously used for the purpose described is designed with a wedge-shaped end formed with a shoulder and longitudinal ribs 011 its extension. This form of nail has also been found unsatisfactory in use as the driving end of the extension breaks the fibers of the leather so'that the top lift does not grip itself securely thereto. This style of nail must also be constructed by special forming operations on its extensions instead of by simply rolling it so that it is much more expensive to manufacture than the improved form of nail herein shown and described.

As before indicated I do not herein claim broadly a heel nail formed with an annular collar at one end and having an extension projecting upwardly tl1erefrom."-'Theparticular features'of my invention which constitute novelty reside in the peculiar formation of the extension on'the'nail whereby it may be more easily penetratedint'o the top lift without breaking the fibers thereof; the annular grooving of the extension'to'provide for the gripping of the top lift thereto 'and the provision for forming the nail by a rolling process whereby it may be manufactured at a relatively small cost to adapt it for generaluse."' What I claim is An improved heel-nail having an extended 1 body portionco'nstructed from round wire, a driving point'at its end, an 'annularcollar flanged out from the body'at its opposite end, and an extension projecting upwardly from said collar, said extension being of substantially the same diameter'as the body of the nail and scored on its periphery with 'a plurality of annular grooves dividing it into a BEST 1%! fslUs-QLE 56? series of spherical beads, the end of the ex- In testimony whereof I affix my signature tenslon being rounded ofl'. to provide for its in presence of tWo Witnesses. easy penetration into the top lift of the heel and having its sides presenting a smooth JAMES KENYON' surface without sharp edges liable to break Witnesses:
